Synopsis

Yuuta's classmate, Makoto Isshiki, comes to Yuuta for advice after receiving an anonymous love letter, thinking it might be from Shinka.

When he comes across Rikka's clubroom to talk to Yuuta, he bears witness to Shinka's true nature as she feuds with Sanae. As Makoto is promptly told by Shinka to forget what he saw, he accidentally drops his notepad, containing a ranking of the girls in school. It is soon found by one of the girls and is brought to the class' attention, which Makoto reluctantly owns up to in order to protect the other boys, unintentionally offering to shave his head in apology.

After being forced to go through with it, Makoto goes to the meeting point, but the writer doesn't show. Later that night, Yuuta is approached by Tōka, asking him to join her and Rikka on their summer vacation.
